00:00:44When our ship conducts on-site observations in the North Pole, in addition to making synchronous satellite observations on the ice surface, in order to make up for the difference in scale between satellites and the ice surface, we will also
00:00:48use drones equipped with different sensors to conduct a detailed survey of the sea ice around
00:00:52the hull , as well as the sensors
00:00:56mounted on the shallow air .
00:01:00We can obtain information about the ocean and the bottom of the ice
00:01:03. Through such cross-disciplinary observation data
00:01:07from different layers from microscopic to
00:01:11macroscopic, we can build
00:01:15a rich, three-dimensional observation
00:01:19model. Through the establishment of this system, we have also tested many
00:01:23domestically produced observation equipment for multidisciplinary cross-research
00:01:26in Beijing. The research center, the school sent me to participate in
00:02:00this male scientific expedition. The main task was for me to
00:02:04serve a domestically produced equipment's first
00:02:07demonstration flight in the South Pole. We chose a good day.
00:02:11Before departure, we found that the weather that day was particularly good
00:02:15, so the route we planned
00:02:18was also the longest route of the entire scientific expedition that year. We used
00:02:22up 1601 seven or eight hours of flight time. Before getting on the plane,
00:02:26we habitually had to control water intake and eating.
00:02:31Because this kind of scientific expedition plane does not have a dedicated place. And we
00:02:34were wearing thick flight suits and a one-piece overalls, it was also difficult to
00:02:38go to the toilet on the plane, so we generally would eat and drink some water
00:02:42after getting off the plane to replenish energy. During
00:02:46this flight, we also encountered some unexpected situations. The original scheduled
00:02:49flight altitude was 3000 meters, and then our first phase of equipment was working
00:02:53stably .
00:02:56The indoor and outdoor
00:03:30temperatures were the same, so at that time
00:03:34I felt very uncomfortable,
00:03:37and the captain reminded us to quickly inhale oxygen, so I had an oxygen tube
00:03:41in front of my nose. At that time, when the oxygen came in, I felt so refreshed.
00:03:45Later, we reached an altitude of 5000 meters and flew normally for a period of time. After
00:03:49we eliminated the danger, we very smoothly completed
00:03:53the next few hours of tasks, and the data from this
00:03:57flight was also perfect. Although we encountered
00:04:00some difficulties of one kind or another, we finally
00:04:04overcame them
00:04:06.
00:04:09When I participated in China's 36th Antarctic scientific expedition,
00:04:12I was already a teacher . After arriving in Antarctica, I saw the Antarctic
00:04:16ice edge and was shocked by the magnificent natural scenery
00:04:20. At the same time, I also experienced what I had seen on the computer
00:04:23screen, these Antarctic sea ice , icebergs
00:04:27, and truly being on site
00:04:31to touch them personally and measure them personally
00:04:35, these phenomena truly brought a very
00:04:39different feeling. At that time, I made a decision in front of the Antarctic
00:04:42icebergs, hoping that my remaining life could be more
00:04:46exciting and that I could see more of the world
00:04:49. After returning from the Antarctic, I
00:04:53transferred to Sun Yat-sen University. At that time, it was because of this opportunity that Sun Yat-sen University
00:04:57took over this icebreaker , and we
00:05:00transformed it into a scientific research ship. I think this historical event is very
00:05:04crucial for the training of polar talents for our entire country
00:05:08. Therefore, I went from being a person
00:05:12relying on a platform to a person building a platform
00:05:16. Because our scientific research ship is a highly efficient
00:05:19scientific research ship, our main goals are two. One is
00:05:23to conduct scientific exploration. The second is that we will also undertake the role of
00:05:27popularizing science . Let's look at this
00:05:31deck. It's very large. Here there are orange
00:05:35steel support equipment . This
00:05:38is a folding crane . We see that there are parameters written on this folding crane. 20 meters.
00:07:42The polar scientific research icebreaker. When we organized the 2024
00:07:46North Pole scientific expedition, we also experienced many, many firsts
00:07:50. When I participated in the Antarctic scientific expedition, I was an ordinary team
00:07:53member. All the scientific expedition plans, I only needed to take care of
00:07:57my own needs. But when we organized
00:08:01the voyage ourselves, we encountered many difficulties. When we made our maiden voyage
00:08:05in 2024, there were 36 scientific expedition members
00:08:08from more than a dozen different universities and scientific research institutes.
00:08:12All of these scientific expedition members, we all have to take the sea survival training
00:08:16. In two weeks, we learned various escape skills, such
00:08:20as a ship fire, or water ingress, abandoning ship,
00:08:23how many enemies it has, where we should gather when we are in danger,
00:08:27what kind of reaction we should make, how to board our lifeboat,
00:08:31etc. These are all some skills
00:08:35that we should know in this extreme environment
00:08:38of the polar regions, in case of various unexpected dangers.
00:09:16In fact, the biggest challenge of scientific expeditions in Beijing
00:09:19comes from polar bears. Polar bears are inherently the dominant
00:09:23creatures in the Arctic. When we conduct scientific expeditions in the Arctic Ocean, we also
00:09:27have special emergency plans
00:09:30to prevent bears. We will also have a special
00:09:34cage. Some students say that this cage is used to hold polar bears.
00:09:37In fact, the opposite is true. These cages are used to hold scientific researchers
00:09:41. That is, when there are team members working on the ice,
00:09:45we will have another group of team members in our cockpit,
00:09:49and there will be lookouts in all directions
00:09:51.
00:09:55The main purpose is to distinguish if there are moving
00:09:59animals approaching. In fact, polar bears have white fur
00:10:03on their bodies, so they are very easy to camouflage in this broken ice
00:10:07and are very difficult to see. Once we find
00:10:10a polar bear approaching.
00:12:25Hello everyone, welcome to the first China Television Youth Open Class
00:12:29of CCTV. I am the host He Yanko. Welcome
00:12:33everyone .
00:12:37Today, we turn our attention to a very distant place, the two
00:12:40poles of the Earth. In fact, for many of us who have never been to the North or
00:12:44South Poles, it may be a mysterious place
00:12:48like a distant land. So, in the hearts of scientists, what kind of place are
00:12:52the North and South Poles ?
00:14:03In fact, seeing you, especially after watching this short film, because many of our
00:14:07colleagues also followed the Xuelong to interview for half a year, they
00:14:11also came back and told me that it was too difficult. Was there
00:14:14a moment when you doubted yourself, "Can I really do it?"
00:14:17At that time, I had also heard from
00:14:21my predecessors how scary the Westerlies were. Some people said
00:14:25to hold the bucket and keep vomiting. Some colleagues
00:14:29were lying in bed and couldn't get up, and it was even
00:14:32rumored that some were tied to the bed
00:14:36for fear of them jumping into the sea . Couldn't take it anymore.
00:14:40Yes. Then, I was relatively lucky
00:14:44when I experienced the Westerlies. Because with the development of
00:14:48scientific polar expeditions, our weather forecasts have become more and more accurate.
00:14:52So, when the ship passed the Westerlies, we actually
00:15:25passed through it in a short time. Yes, we describe it as swaying
00:15:29from side to side and rocking back and forth.
00:15:33So, it sways front, back, left, and right.
00:15:36How long does this state last?
00:16:08I am far away from home, far away from my relatives, far away from
00:16:12my familiar environment, and I have been away for such a long time. I went to the South Pole
00:16:16in November 2019, and then we had to take Xuelong and Xuelong 2 back
00:16:19home. At that time, my two children were still quite young. We
00:16:23left Zhongshan Station, and it was delayed for a month, and then we had to take
00:16:27the ship for 44 days to go back . So suddenly this time
00:16:30was more than two months before I could see them, so I
00:16:34called home. My two children were crying.
00:17:37Is there any other way to go back ? Then my son said,
00:17:40"Then you can still take the boat." But
00:17:44taking the boat might take longer, maybe more than a month
00:17:47. Then my daughter was even more playful. "Mom, you can still swim."
00:17:51So later, I guided
00:17:55them to find the answers themselves, and they could understand why I still
00:17:58had to wait so long to get home. So later, after calling
00:18:02and asking, they could understand.
00:18:06"Okay, Mom, we're
00:18:13waiting for you at home." In fact, for children, it's not just these two months,
00:18:17you may be absent for many months during their growth.
00:18:21Do they understand ? They understand and don't understand
00:18:24.
00:18:32But when they encounter difficulties, especially when they are sick,
00:18:36they will also complain. Yes, so
00:18:40when I went to the North Pole in 2024, before I left, they were
00:18:43also very reluctant and said, "Why do you always
00:18:47go? Can this be the last time?" But
00:18:51I reluctantly agreed
00:18:53. But I believe that when they grow up, they
00:18:57will be proud of you .
00:18:59Just now, I was watching your
00:19:06short film and listening to your story .
00:19:10I want to ask you. The first one is very
00:19:14. Besides scientific research tools, what
00:19:16personal items
00:19:23do you take to the polar regions
00:19:26for exploration ? One is to
00:19:30satisfy our appetite, right? We
00:19:34will definitely bring delicious food. The other is a fork and spoon
00:20:50. When we work in China, we may have to process 800 messages every day.
00:21:12Because you have collected a lot of data. We will be very anxious to see how
00:21:16these data are ?
00:22:20Also, let them come. First, who will come ? Okay
00:22:23.
00:22:26Hello host, hello Teacher Zhao. I am also from Jingzhou, Hubei. Fellow villager
00:22:30.
00:22:33At first, I was also in the record of China's great No. 2 icebreaker.
00:22:36Then I slowly recorded works, and then, starting from Southeast Asia,
00:22:40then to Europe, and finally to the South Pole. So amazing
00:22:43. Oh, you've been to the South Pole. Yes, I have been to the South Pole. Because it was my first time
00:22:47there, like the snow mountain and the glacier,
00:22:51especially the glacier, because it is really very lovely. At that time, I was taking
00:22:55pictures on the bed and took such a picture
00:22:58. Wow, it's so beautiful. Behind is a huge
00:23:02iceberg, and in front are small penguins
00:23:04.
00:23:09Generally, what we see are Adélie penguins, whose
00:23:13size is slightly smaller . When
00:23:16we were doing research in the snow,
00:23:19these penguins would simply walk past you,
00:23:23and some were very curious and would come to peck at what we were doing.
00:23:27And they are not afraid of people. And they run very fast.
00:23:30Once I wanted to take a picture with a penguin, and then the penguin
00:23:34ran a few steps and then slid on the ice with its belly, and
00:23:38it ran far away in an instant, and I couldn't catch up with it at all. In the North Pole,
00:23:42it's actually polar bears
00:23:43.
00:23:49Um. When our team members set off, we did safety training and saw
00:23:53that we must not feed polar bears. We also
00:23:56have a joke that if we really encounter a polar bear and have to run, I may not
00:24:00be able to run very fast, but as long as I am not the last one, it's fine
00:24:03. Polar bears actually move very fast
00:24:07. They are also very fast . Because I have seen polar bears
00:24:11in the zoo, when they stand up, they are very tall, so they may not
00:24:15be as cute as they seem
00:24:18.
00:24:50In this urban environment, it is affected by the entire Earth's
00:24:53climate system. This is also the most important reason
00:24:57why we go to the Arctic for scientific research. If the Arctic sea ice completely disappears
00:25:01in summer, it will significantly affect our Arctic shipping, and will also affect
00:25:05the entire Arctic Ocean ecosystem, such as polar bears
00:25:09and seals, which rely on sea ice to survive . These higher mammals
00:25:13may lose their homes. There are also some ocean
00:25:16creatures that will produce huge changes due to light conditions.
00:25:50I feel that your experience should be even more intense. Day
00:25:54after day, with the same scenery, will you feel bored? Will you feel
00:25:57unmotivated ?
00:25:59Open the half-door window,
00:26:32and outside the window is the sea and icebergs.
00:26:36Every day on the road, I would think, why was this iceberg here yesterday, and
00:26:40now it has drifted here today? Then our
00:26:44team members would even name the icebergs, saying, "This iceberg is mine,
00:26:48I want to call it something." We would find
00:26:51these unique joys in the daily scientific expeditions,
00:26:55and we would also be curious about some phenomena
00:26:58we discovered on site, because they are originally ours.
00:27:32To be honest, at that time, on the last day when I was walking back
00:27:36from completing the task, it was announced that we were returning,
00:27:40and on the way back, because the sea ice had already melted
00:27:44in the low-latitude areas, I was actually very disappointed,
00:27:47because I didn't know when
00:27:51I would be able to come back to the North Pole again. Full of reluctance. Yes, then
00:27:54that night I sat in my room and cried
00:27:58loudly. I think this is the difference between scientific researchers
00:28:02and us regarding such extreme environments. Perhaps for us, the most
00:28:06beautiful scenery may gradually become
00:28:10bland over time. But for scientists,
00:28:14this is an endless source of inspiration, because it is the fertile ground
00:28:18of science, constantly generating the motivation to continue research
00:28:22. I really admire you
00:28:24.
00:28:30Is there any other friend who wants to ask a question ? Come
00:28:32on, you. Hello host, hello Teacher Zhao
00:28:36. My name is Yang Tian, and I am a doctoral student at Sun Yat-sen University
00:28:40. It is an honor that I was also a teammate of Teacher Zhao
00:28:43on Sun Yat-sen University's second Arctic voyage in 2024. You two
00:28:47together .
00:28:50Yes. Today, I can be considered to be sharing a little secret. Because
00:28:54we lived together on the ship for more than 70 days of scientific expedition
00:28:57, everyone might have just felt that it was a very emotional
00:29:01and very
00:30:33wearing it and then crawling
00:30:34down.
00:30:37So I was thinking, just now, Teacher Zhao, you are also considered
00:30:40an old polar explorer, right ? How come in this
00:30:44situation, a piece of ice , a set of data,
00:30:48can still greatly arouse your spirit of exploration or curiosity
00:30:51? Indeed, I remember what he said, because when we were conducting
00:30:55an Arctic expedition, it was under extreme
00:30:58conditions, that is,
